Been busy in the shop, went a few days without taking photos. oops.
I think I've finally settled on the final patina process.. It starts with a 2 day rusting process, then stripping back the rust with boiling vinegar, then dipping into hot green tea to darken the finish.
Here is what the steel looks like part way through rusting.
Three different examples of steel finishes. On the left - Bare metal, no rusting, etched in vinegar, dipped into green tea, repeat twice. IMO, this finish is too uniform, appears un-authentic.
On the right - Prototype tip that has been naturally aging for months. Started off looking a lot like the steel on the left, but not as dark. Over time it has really darkened up, and the tip closer to the charcoal has a really nice dark brown thing going on.
In the middle - This is the finish that I have settled on. Rusted, vinegar boil, green tea. The finish appears very aged, and will only get better with time.
I may do one last process to make the tips even darker, and add a bit of colour... I'll post some photos of my tester tomorrow.
Turning the cocobolo stem blanks!
Super nice grain!
Some bocote stems on the right. They will appear darker after finishing.
Drilled and faced the mortises for the mouthpieces.
Mouthpieces glued in. The two stems in the foreground are Brazilian teak, It's got some really cool grain upon closer inspection.
